Abstract
Subject matter disclosed herein relates to memory devices and, more particularly, to programming a memory cell.
Claims20
A memory device, comprising:
- a controller configured to program a memory cell to a set state and operate in a first mode and a second mode, the controller comprising:
- a selector configured to:
- select the first mode to program the memory cell to the set state;
- and
- change from the first mode to the second mode based at least in part on a failure to program the memory cell to the set state using the selected first mode.
2 more elements
An apparatus, comprising:
- a memory array comprising a memory cell;
- a controller coupled with the memory array and configured to select a first mode and a second mode as an operational mode for programming the memory cell based at least in part on a failure to program the memory cell to a set state, the controller comprising:
- a selector to select the first mode as the operational mode of the controller;
- a first node to apply a first signal to the memory cell to program the memory cell to the set state based at least in part on the first mode;
- a detector to identify the failure to program the memory cell after the first signal is applied, wherein the selector is configured to select the second mode as the operational mode based at least in part on the failure;
- and
- a second node to apply a second signal to the memory cell to program the memory cell to the set state based at least in part on the second mode.
4 more elements
A method comprising:
- selecting a first mode as an operational mode of a controller coupled with a memory cell;
- performing a first operation to program the memory cell to a set state based at least in part on the selected first mode;
- determining that the first operation failed to program the memory cell to the set state;
- and
- selecting a second mode as the operational mode based at least in part on the first operation failing.
